Spatial characterization of Vs at Amherst NGES sitefrom SCPT using Bayesian kriging

This paper illustrates a case study application of geostatistical kriging to shear wave velocity measurements from seismic piezocone (SCPT) testing in clay at the Amherst national geotechnical experimentation site (NGES) site. Analyses are performed in a pseudo-3D perspective, by which data are clustered into samples based on measurement depth. Bayesian kriging is performed at each depth cluster. The site-specific operational procedure is described, with particular reference to important aspects such as the identification of best-fit semivariogram parameters.
